Environmental, economic, and social sustainability in aquaculture: the aquaculture performance indicators.

Aquaculture is a rapidly growing food production technology, but there are significant concerns related to its environmental impact and adverse social effects. We examine aquaculture outcomes in a three pillars of sustainability framework by analyzing data collected using the Aquaculture Performance Indicators. Using this approach, comparable data has been collected for 57 aquaculture systems worldwide on 88 metrics that measure social, economic, or environmental outcomes.

Aquatic food loss and waste rate in the United States is half of earlier estimates.

Food loss and waste (FLW) is a major challenge to food system sustainability, including aquatic foods. We investigated aquatic FLW in the food supply of the United States, the largest importer of aquatic food globally, using primary and secondary data and life cycle methodology. We show that there are significant differences in FLW among species, production technology, origin and stage of supply chain.

The economic impact of decreased mortality and increased growth associated with preventing, replacing or improving current methods for delousing farmed Atlantic salmon in Norway.

Impacts of salmon lice is a major concern for a sustainable production of farmed Atlantic salmon in Norway. Most treatment methods for removal of salmon lice have associated increased mortality and decreased growth in a period after delousing, which affects the profitability of the farmer, and causes poor welfare and sustainability. In addition, the variance in mortality and growth, especially after non-medicinal treatment methods, is high, which makes it hard for a farmer to decide which control measure to apply to keep lice levels below the legal limit.

The Covid-19 impacts on the European Union aquaculture sector.

There have been a number of indications of strong negative impacts of Covid-19 and the preventive measures associated with the pandemic for all food sectors. However, there is increasing evidence that the picture is quite nuanced where the Covid related measures are creating challenges for some and opportunities for others. In this paper we investigate the impacts of Covid-19 on the aquaculture sector in the European Union using two approaches; a survey where industry representatives and experts assess the impacts on key economic indicators allowing for positive as well as negative impacts, and recently published aquaculture production data for Denmark and Spain.
